The wood plastic composite panel according to the present invention has excellent strength and durability. Furthermore, the wood plastic composite panel according to the present invention exhibits excellent appearance and texture comparable with cut-open surfaces of natural lumbers although the panel has a surface structure different from the cut-open surfaces of the natural lumbers.
Description
Technical field
The present invention relates to a kind of new wood plastic composite panel that has with natural timber similar in appearance and texture, and more specifically, relate to a kind of wood plastic composite panel of making by resin composite materials, in described resin composite materials, disperse wood-fibred in the synthetic resin parent equably with preliminary dimension, and this sheet material has the wood pattern (woodpattern) that forms in its surface, wherein, common formation has the boss structure of desired depth and has the linear micro concave male structure of desired depth on the whole surface of this sheet material, thereby presents outward appearance and the texture closely similar with the section of natural timber.
Background technology
Use the problem of the construction material existence of natural timber to be: because water or sunlight, the former state or the texture of construction material damage easily.Reason has been carried out big quantity research to develop a kind of radwood composite wood that can eliminate the natural timber problem for this reason.By mixing granular or pellet shapes wood-fibred and synthetic resin, add multiple additives according to product purpose, and employing is pushed or injection makes this mixture form the shape of sheet material and make the radwood composite wood with the predetermined mix ratio.
Yet, in the wood plastic composite panel of making as mentioned above, after extruding, on the surface of this sheet material, constitutes skin as the synthetic resin of the precursor composition of resin composite materials.As a result, though use wood-fibred as filler, because distinctive oil-like tactile sensation of plastics and high glaze can not provide distinctive outward appearance of natural timber and texture.Therefore, the problems referred to above that multiple trial solves wood plastic composite panel have been carried out.
Particularly, carried out several trials and had intrinsic outward appearance of natural timber or superficial makings for making wood plastic composite panel.For example, adopt following method usually: use to have the method that color dye is pushed; The method of artificial wood pattern; The method of the method for transfer printing or printing wood pattern and the film of the wood pattern that lamination has natural timber or artificial material.Yet these methods exist manufacture method very complicated usually, and in some cases, can reduce the problem of durability of products.
In order to address the above problem, a kind of boss structure that forms has been proposed on the surface of wood plastic composite panel so that the method for wood pattern directly to be provided to the surface of wood plastic composite panel.This method has been omitted aforesaid back process operation, and therefore, the wood plastic composite panel that makes manufacturing have high-durability, reduction manufacturing cost becomes possibility.Though the wood plastic composite panel of Zhi Zaoing presents and the most similar wood pattern of natural timber section by this method, but this wood plastic composite panel has high glaze, and when the user contacted this wood plastic composite panel, the user can feel the distinctive oil-like tactile sensation of synthetic resin.As a result, though wood pattern may be provided, the luxurious outward appearance and the texture that provide natural timber can be restricted.
Also propose a kind of size of using and be about 40～60 purpose large scale wood-fibreds provide the texture of natural timber thus with the percentage that increases the wood-fibred that directly is exposed to plate surface as filler method.Yet because the wood-fibred size increases the coupling power that can reduce wood-fibred, therefore, the intensity of sheet material can descend.Equally, wood-fibred is exposed to the surface of sheet material brokenly, and therefore, texture can reduce.
Under the situation by direct processing natural timber manufacturing natural lumber panel, after the surface of the natural lumber panel of processing and manufacturing glossily, natural lumber panel has presented fabulous outward appearance and texture.Therefore, the high-quality natural lumber panel of usually surface complicated processing the being crossed inside and outside decoration that is used to build.Surface-treated natural lumber panel has graceful wood pattern, level and smooth and soft texture, and suitable gloss.As a result, make and show wood pattern ideally and become possibility.This is by the compound action realization of the physical property of the uniqueness of the cellulosic polymer that constitutes timber and natural timber tissue.
On the other hand, when handling radwood composite wood surperficial glossily in the mode identical with natural timber, this radwood composite wood presents distinctive high glaze of synthetic resin and oil-like tactile sensation.Therefore, although used the resin composite materials that comprises synthetic resin and wood-fibred, press for and a kind ofly be used to provide with natural timber section similar in appearance and texture and reduce the technology of manufacturing cost as raw material.
Summary of the invention
Therefore, carried out the present invention and solved the problems referred to above, and other still unsolved technical problem.
As the multiple extensive research that addresses the above problem and the result of test, the present inventor has been found that, the resin composite materials that comprises the wood-fibred with preliminary dimension when use is during as raw material, and when forming the boss structure of lumber cut-open case on the surface at sheet material and having the linear micro concave male structure of desired depth with desired depth, though described sheet material has the surface texture different with the section of natural timber, described sheet material presents the outward appearance and the texture of the section that is equivalent to natural timber.Based on these discoveries, finished the present invention.
According to the present invention, can realize above-mentioned in the following cases and other purpose: wood plastic composite panel is to be made by resin composite materials, in described resin composite materials, comprise in the synthetic resin parent and be of a size of 80～300 purpose wood-fibreds, described wood plastic composite panel has mean depth on its whole surface be that the boss structure and the mean depth of the lumber cut-open case of 200～900 μ m is the linear micro concave male structure of 10～500 μ m, when light was incident to described sheet material surperficial with 60 degree incidence angles, the reflectivity of described sheet material was 10～50%.
Compare with natural wood panel, wood plastic composite panel according to the present invention has fabulous intensity and durability.And can confirm with comparing embodiment by embodiment described below: compare with conventional wood plastic composite panel, wood plastic composite panel according to the present invention has presented outward appearance and closely similar outward appearance and the texture of texture with the section of natural timber.
Comprise as the synthetic resin of precursor composition with as the wood-fibred of filler as the resin composite materials of described wood plastic composite panel material.As long as synthetic resin is to have with the high-compatibility of wood-fibred and have high strength and the fluoropolymer resin of durability, described synthetic resin is not particularly limited.Preferably, can use as polyethylene, polypropylene and polystyrene based on polyolefinic poly-fluoropolymer resin as synthetic resin.
Described wood-fibred comprises by natural timber or regeneration timber being ground to form the short fiber that wood powder that the shape of particulate or pill makes and the natural fiber (for example, hemp, flax (flex), jute, mestha, cellulose etc.) by other kind of cutting make to predetermined length.Though the percentage by weight of described wood-fibred can change according to the purposes of wood plastic composite panel, based on the gross weight of resin composite materials, described wood-fibred can occupy about 20～80 weight %, is preferably 30～50 weight %.Yet when the content of wood-fibred very little the time, the content of synthetic resin increases relatively, therefore, is difficult to provide be equivalent to appearance of natural wood or texture.On the other hand, when the content of wood-fibred was too many, the content of synthetic resin reduced relatively, and therefore, the coupling power of wood-fibred reduces.Therefore, be difficult to provide the intensity and the durability of expected degree.
As mentioned above, described wood-fibred is of a size of 80～300 orders, is preferably 90～150 orders.When the size of wood-fibred was too big, the intensity of sheet material can reduce, and the surface of sheet material can be very coarse, and therefore the outward appearance that is equivalent to the natural timber section or the luxurious outward appearance or the texture of texture can not be provided.On the other hand, when the size of wood-fibred too hour, the distribution meeting heterogeneity of the wood-fibred in the resin composite materials.Especially, though sheet material has boss structure and micro concavo-convex structure, can not make this wood plastic composite panel present the outward appearance and the texture of expectation, this point will be described in more detail below.
According to the purposes of sheet material, can add multiple composition to described resin composite materials.
Usually, thus can add pigment to resin composite materials can provide different colours for multiple timber.Preferably,, in resin composite materials, add inorganic pigment, therefore, can keep its inherent colour for a long time because cause that by daylight the possibility of its variable color is low.Can use described pigment separately.Yet,, can use the combination that comprises two or more pigment with the performance different colours according to details.
At the boss structure and linear micro concave male structure that have the lumber cut-open case of desired depth according to the common formation in the surface of wood plastic composite panel of the present invention with desired depth, therefore, by the compound action of the boss structure in the resin composite materials, linear micro concave male structure and wood powder, described sheet material can present the outward appearance and the texture of the section that is equivalent to natural timber.
When natural timber is cut into the shape of sheet material, occur on the surface of timber natural timber exclusive pattern (" lumber cut-open case "), for example grain of wood and annular ring.Described boss structure has the pattern that is equivalent to the lumber cut-open case.In addition, boss structure according to the present invention has desired depth, and therefore, described boss structure makes its outward appearance that presents the section that is equivalent to natural timber and texture together with the linear micro concave male structure.Particularly, verified, when the surface at sheet material only formed the boss structure of lumber cut-open case, this sheet material can present the graceful pattern of natural timber fully.Yet verified, the physical property of forming the synthetic resin of resin composite materials can show on the surface of described sheet material, and therefore, this sheet material can not provide unique physical character, the especially texture of natural timber.On the other hand, verified, when the surface at sheet material only forms the linear micro concave male structure, can greatly weaken the unique physical character of synthetic resin; Yet, unique physical character, the especially You Mei outward appearance of natural timber can not be provided.In addition, verified, when described boss structure and described linear micro concave male structure satisfy following actual conditions, the effect that described boss structure and described linear micro concave male structure provide the present invention to seek.
According to the present invention, the common mean depth that forms is that the boss structure and the mean depth of the lumber cut-open case of 200～900 μ m, preferred 500～600 μ m is the linear micro concave male structure of 10～500 μ m, preferred 200～300 μ m on the surface of described wood plastic composite panel.Have 10～50%, preferred 10～30% reflectivity in the time of must making light be incident to described sheet material surperficial and be identified for the boss structure of sheet material and the size of micro concavo-convex structure with 60 degree incidence angles.According to the present invention, common formation has the boss structure of certain depth and has the micro concavo-convex structure of certain depth so that described sheet material has specific reflectivity on the surface of described sheet material, therefore, this sheet material presents the outward appearance and the texture that can compare favourably with the natural timber section.
Can form described boss structure on the surface of described sheet material by for example on the surface of sheet material, pressing hot dandy roll.When the degree of depth of boss structure was too little or too big, the distance between the protrusion of boss structure can be too narrow or too wide.As a result, the oil-like tactile sensation of synthetic resin can strengthen, and can increase at the light reflectivity on the surface of sheet material.Therefore, this sheet material can not present appearance of natural wood and texture.
Can form described micro concavo-convex structure by sandblast and brush sand.Particularly, so that being exposed to the surface of sheet material and forming small recesses by the surface at sheet material, wood powder forms described micro concavo-convex structure by removing some synthetic resin layers from the surface of sheet material.When the degree of depth of micro concavo-convex structure too hour, can not fully eliminate the oil-like tactile sensation of synthetic resin.On the other hand, when the degree of depth of micro concavo-convex structure was too big, the boss structure of this lumber cut-open case can excessive damage.
Different with the boss structure of lumber cut-open case, described micro concavo-convex structure is formed on the surface of sheet material with linearity configuration.Preferably, described micro concavo-convex structure can be formed on the surface of sheet material abreast with the grain of wood of lumber cut-open case.
